-1,079. Specification of 1mm Ihteat. Patented Nov. 25, 1913.

To all whom it may concern Be it known that I, Gnonon R. CORNWALL, a citizen of the United States, residing at Rye, in the county of Westchester and State of New York, have invented new and useful Improvements in Types, of which the following is a specification;

The invention relates to interchangeable, settable-t pes and has for an object the pro viding 0 types which effect an nnpression by the action impressed and not by the action of 111k or similar medium placed upon theface of the type for the purpose of making an impression upon the character-receiving surface. These and other objects will more fully appear from the following description.

The invention consists in the novel articles, parts, andv combinations herein shown and described.

The accom anying drawing, referred to herein and orming a part hereof, illustrate an embodiment of the invention, the same serving in connection with the description herein-to explain the principles of the invention. p

Of the drawings: Figure 1 illustrates one formof type; Figs. 2 and 3' are edge views of a type such as is shown in Fig. 1; Figs. 4 and 5 show a similar type with a different form of joining and alining means; Fig. 6 illustrates a type having a light-arresting body and a light-transmitting character; Figs. 7 and 8 are end views of the character such as is shown in Fig. 6, showing various forms of joining and alining means; Fig. 9 shows a modified form of type; Fig. 10 shows a chase carrying a form made up of types of a character included in this invention; and Fig. 11 shows a chase carrying a form made up of another character of types included in this invention.

In the embodiment of the invention illustrated in the drawings herewith, a type body 1 is shown which is of a material that transmits light and bearing a character 2 which is of a light-arresting nature. The type may be provided, if desired, with locating and alining means for cooperation with similar means on adjacent types, and such means are herein illustrated as a proud portion 3 on two edges thereof and a recessed portion 4 on the two corresponding edges, for the urpose of permitting adjacent types to be oined together in proper alinement. In

of light upon the surface to be Application filed April 17, 1905. Serial-Io. 250,122.

Fig. 3 of the drawings a character is shown upon both. faces ofthe type body while in F g. 2 1t is shown upon only one facer In Figs. 4 and 5 are shown locating and alinmg means of a different character.

. In Fig. 6 of the dra-win is shown a type body 1 which is of a lig t-arresting cha1 acter and which bears a character 2' which is of a li ht-transmitting nature. The type body-in t is case may also be provided with sultably designed portions, some forms of which are shown in Figs. 7 and 8, for the purpose of locating and alining adjacent types. In this case the said alining portions may also be of a light-arresting nature orv character. I

In Fig. 9-of the drawings is shown a form of type m which a protecting plate or surface 2", which may be of a light-transmitting medium, is placed over the characterbearing surface of the type. It-is obvious that this may be applied to either the form in which the character is light-transmitting or light-arresting.

In Figs. 10 and 11 are shown formsof the characters described locked up in chases. In the form shown in Fig. 10 the surface surrounding the form within and without the chase where the plate extends beyond the form may be covered over with a lightarresting material, shown in the drawings as 5, in order that the action of the light upon the plate may take placeonly through :the characters. In the form of the invention lllustrated in Fig.11 where the plate is of greater extent than the form, furniture and other locking means may be provided which is of a light-transmitting nature.

Types of this character may be used for the purpose of acting upon a sensitive surface, and this may be done in any suitable manner. A convenient way of doing this is to place the form and plate in contact, with the character-bearing faces of the types, if

desired, in contact with the sensitive surface of the plate. The plate may then be developed. and prepared for planographic printing, or it may, by etching properly, be made into a relief or intaglio printing surface.

The types of the character included in this invention may be made in various Ways. The surface of the types may be sensitized and the character may be photographed thereon, and development of the surface may be of a nature so as to render the non character part of the surface'light-arresting. This will be the case Where, for instance, a silver salt is the light-sensitive element of the sen-' sitized surface. The surface of the types ma also be pre ared in various other wa s, as y coatin tiie surface of the type with sensitive asp alt which may then. then photographing thereon, or impressing thereon by means of the action oflight through a negative, the character desired manner known to the art, and after ex osure to the light under a form such as is erem shown, the surface of the plate may be developed and be repared for printing planngraphically, or y being rolled up in an acid resist it may be etched away and used as a relief or intaglio plate as hereinbeforeindicated.

From the foregoing it will be understood that a new variety of types has been rovided which is of great usefulness; wiiich may be quickly made up into forms, including types of various sizes; which are adapted to produce either a planographic or relief printing surface; which, while susceptible of a variety of uses, lend themselves readily to the makin up of job work for printing on a planograp ic rotary press, thus yielding work of a very high character, and at great speed; besides possessing many other advantages.

The invention, in its broader aspects, is

dried,

not limited to the particular constructions shown, nor to any particular constructions by which it has been or may be carried into effect, as many changes may be made in the construction without departing from the main principles of the invention and without sacrificing its chief advantages.

What I do claim as m invention, and desire to secure by Letters latent, is

1. An interchangeable settable type body bearing a character, the portion constitutin the character and the re aining portion 0 the type body, respective site action with respect to the transmission of light.

2. An interchangeable settable type body 1 comprising a light-transmitting character, the remainder of said type body being lightarresting.

3. An interchangeable settable type body bearing a character, said character and the remaining parts of said type body being of opposite qualities as regards the transmission of light, said typebody being provided y, being of oppoob with a proud portion for the (purpose of engaging with adjacent type bo es.

I 4. An interchangeable settable type body bearing a character, the portion constituting the character and the remaining portion of the type body being of opposite act-ion with respect to tie transmission of light, said type body being provided with means for preventing the action of light about the edges of the type body.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

GEORGE R. CORNWALL.
